[Zope] Disappearing data?

[Chris Larson]

I finally got Zope up and running, and started working my way through the 
Plutonia quick start in the ZMG.

Made a few changes, saved them by clicking on the change button. I had 
added three folders, changed a couple of items, then left for about 4 
hours.

When I got back, I started looking again, clicked on the properties tab, 
added a date property, clicked on change, and got a message back saying 
roughly that the data didn't exist.

I clicked on reload, and was rewarded with essentially a virgin 
installation. That is, everything I had changed or added was gone, and 
the data visible was just what I saw when I first started.

One of the first things I had done was make the standard background color 
"FFFFEE" instead of "FFFFFF". Even that had reverted.

What's the deal here? Am I missing some login/logout or confirm changes 
this session option?
